The DeleteTable operation deletes a table and all of its items.
After a DeleteTable request, the specified table is in the
DELETING state until DynamoDB completes the deletion. If
the table is in the ACTIVE state, you can delete it. If a
table is in CREATING or UPDATING states,
then DynamoDB returns a
ResourceInUseException . If the specified
table does not exist, DynamoDB returns a
ResourceNotFoundException . If table is already in the
DELETING state, no error is returned.

NOTE: DynamoDB might continue to accept data read and write
operations, such as GetItem and PutItem, on a table in the DELETING
state until the table deletion is complete.
